また、`from starlette import status`を使うこともできます。

**FastAPI** は、`開発者の利便性を考慮して、fastapi.status`と同じ`starlette.status`を提供しています。しかし、これはStarletteから直接提供されています。

## デフォルトの変更

///

Это позволит:

* Возвращать указанный код статуса в ответе.
* Документировать его как код статуса ответа в OpenAPI схеме (а значит, и в пользовательском интерфейсе):

<img src="/img/tutorial/response-status-code/image01.png">

/// note | "Примечание"

Некоторые коды статуса ответа (см. следующий раздел) указывают на то, что ответ не имеет тела.

**NOTE:**

sets, which is *16* 64 = 1024* drives in total.

- *If total number of nodes are of odd number then GCD algorithm provides affinity towards odd number erasure sets to provide for uniform distribution across nodes*. This is to ensure that same number of drives are pariticipating in any erasure set. For example if you have 2 nodes with 180 drives then GCD is 15 but this would lead to uneven distribution, one of the nodes would participate more drives. To avoid this the affinity is given towards...

`status_code` 매개변수는:

* 응답에서 해당 상태 코드를 반환합니다.
* 상태 코드를 OpenAPI 스키마(및 사용자 인터페이스)에 문서화 합니다.

/// note | "참고"

어떤 응답 코드들은 해당 응답에 본문이 없다는 것을 의미하기도 합니다 (다음 항목 참고).

이에 따라 FastAPI는 응답 본문이 없음을 명시하는 OpenAPI를 생성합니다.

这只是一种快捷方式，具有相同的数字代码，但它可以使用编辑器的自动补全功能：

/// note | "技术细节"

也可以使用 `from starlette import status`。

为了让开发者更方便，**FastAPI** 提供了与 `starlette.status` 完全相同的 `fastapi.status`。但它直接来自于 Starlette。

- Improved scheduling performance when many nodes, and prefilter returned 1-2 nodes (e.g. daemonset)
